This article studies the temporality of platform labor through the specific lens of Meituan, the leading food delivery platform in China featuring an algorithm-driven dispatch system. This paper widens the existing research on platform labor from the perspective of time and speed. The on-demand food delivery service cultivates consumers’ expectations of timely satisfaction, nonetheless, it builds upon the rush, strictness, and flexibility of digital labor’s temporality which is often called a “mission impossible at times”. With the rhetoric of ‘Flexible work hours,’ the platform acts as an intermediary in the contradictory costumer-rider temporal relationship and prioritizes the customer's position within the temporal orders, where ICTs such as real-time tracking systems play a key role in sense-making. As the article will show, Meituan’s ETA (Estimated Time of Arrival) algorithm distributes the common interests of efficiency with the "invisible hand of value," in the quaternary relation between riders, customers, suppliers, and platform. While workers' time experience and negotiating ability are diminished, the platform gains the ultimate capacity to exploit platform labor systematically. The coordination of all platform algorithms normalizes class divisions and unequal power structures, interpreting the asymmetrical power between capital and labor in the platform economy.
